“Lost in Translation”: what do the negative values of effective Grüneisen coefficients mean in shock wave experiments? [Extended comment on “Shock compression of porous metals and silicates” by A B Medvedev and R F Trunin, Phys. Usp. 55 773 (2012)]


Institute for High Pressure Physics, Russian Academy of Sciences, Kaluzhskoe shosse 14, Troitsk, Moscow, 108840, Russian Federation

The possible reasons for the negative effective Grüneisen coefficient in silicates under shock compression are considered. It is shown that the negative effective values of the Grüneisen and thermal expansion coefficients are, as a rule, a consequence of diffuse structural changes with a change in the short-range order structure in the solid or liquid state. We discuss the thermodynamic and kinetic aspects of these transformations, as well as the possibility of chemical decomposition of compounds at high pressures and temperatures.
